摘　　要：采用数值模拟软件Fluent对100t氧气顶吹转炉三维流场进行数值模拟。通过模拟结果讨论了炉内不同时期气相速度分布、熔池液面冲击形貌和速度分布以及熔池内部不同深度处速度分布情况。研究结果发现,顶吹转炉中熔池液面凹坑处液体具有较大的速度,而在熔池凹坑外部区域速度降低至很小。不同熔池深度处,熔池液体速度随熔池深度的增加衰减较大。熔池内部搅拌弱区位于熔池中心底部和炉壁底部区域。Numerical simulation of the 3-dimensional flow field of the 100 t basic oxygen furnace（BOF） has been carried out by commercial software FLUENT. The gas flow distribution, bath surface morphology and velocity distribution in different periods, and velocity distribution in different bath depth have been analyzed and discussed according to the simulation results. The results show that the maximum velocity appeared at the dent, whereas the velocity decreases obviously at the exterior area of the dent. The bath velocity decreases sharply with the increase of the bath depth. The weak stirring zone lies in the middle-bottom and the edge region of the bath.
